摘要

摘要通过共沉淀法合成了铁（II）锰（II）铁氧体 Mn0.3Fe2.7O4（沉淀物的后续热处理和机械处理有多种选择）。通过粉末 X 射线衍射、红外光谱、扫描电子显微镜和磁力测定法对该材料进行了研究。该粉末在氩气环境下于 740°С 下退火（8.0 小时），并在合成的最后阶段进行了高能研磨（1.0 小时），由于基于该粉末的油悬浮液具有高剪切应力（625 mT 时为 3500 Pa）和高吸油能力，从而确保了悬浮液的沉降稳定性，因此是一种很有前途的磁流变材料功能填料。

Synthesis, Structure, and Magnetic Properties of Mn-Substituted Magnetite for Magnetorheological Materials

Abstract

Iron(II) manganese(II) ferrite Mn_0.3Fe_2.7O₄ was synthesized by co-precipitation (with various options for the subsequent heat and mechanical treatment of the precipitate). The material was studied by powder X-ray diffraction, infrared spectroscopy, scanning electron microscopy, and magnetometry. The powder that was annealed under argon at 740°С (8.0 h) and subjected to high-energy milling (1.0 h) at the final stage of the synthesis is a promising functional filler for magnetorheological materials, owing to high shear stress (3500 Pa at 625 mT) of an oil suspension based on this powder and high oil absorption capacity, which ensures sedimentation stability of the suspension.
